Not Ranked
I went with a complete McLeod super street pro setup with flywheel, TOB and fork. Performs flawlessly. My other choice would be a RAM powergrip HD. I'm not saying you need the dual friction material as I have, you could possibly get chatter for a split second depending on gearing and how smooth you are. I don't. the organic material might be good in your application or a McLeod twin Disc setup which many have.
I have a 351 with 410 RWHP/390 RWTQ 2600lbs curb wt.
